Exploring Biomechanical Correlates in Voice Analysis of Multiple Sclerosis Patients.

Introduction: The predominant alterations in voice of patients with multiple sclerosis (MS) are phonatory instability, vocal asthenia and roughness, shortness of breath, hypophonia, and hypernasality. However, research on alterations of acoustic parameters has few studies and disparate results. The objective of this study was to investigate voice disturbances in patients with MS, both with objective measures (analysis of biomechanical) and subjective measures (scales and questionnaires).

The Systematics of the Trematoda.

The platyhelminth class Trematoda comprises two subclasses with largely disparate species diversity, with the small Aspidogastrea with c.80 species and the speciose Digenea with c.18,000 species, which has attracted much effort towards our understanding of evolutionary relationships among suprageneric taxa.

Biomechanical Parameters of Voice in Parkinson's Disease Patients.

Introduction: Previous research on voice in Parkinson's disease (PD) has consistently demonstrated alterations in acoustic parameters, including fundamental frequency (F0), maximum phonation time, Shimmer, and Jitter. However, investigations into acoustic parameter alterations in individuals with PD are limited.

Methods: We conducted an experimental study involving 20 PD patients (six women and fourteen men).

The genus in Mediterranean scorpaenoids (Teleostei), including the description of n. sp. from (Delaroche, 1809).

More than 65 species of the genus Van Beneden & Hesse, 1863, have been described to date, most of them infecting Perciformes. Among the scorpaenoids (Perciformes, formerly Scorpaeniformes) the species of the genus parasitize sebastids and scorpaenids worldwide. In this study, we provide new morphological and molecular data for spp.

Parasite communities in a marine fish indicate ecological recovery from the impacts of the Prestige oil-spill 12-13 years after the disaster.

The Prestige oil-spill (2002) is one of the major marine accidents resulting in contamination of virtually all types of marine habitat along c.900 km of coastline in the North-East Atlantic. Environmental pollution affects parasite populations and communities, both directly and through effects on intermediate and definitive hosts.
